Cave morays are tier 10 fish found by members in the Daemonheim dungeon, while training Dungeoneering. They can be caught at specific fishing spots throughout dungeons on a complexity level of 2 or higher. Raw cave morays are caught with a fly fishing rod, in conjunction with feathers, by players who have a Fishing level of 90 or higher. They require 90 Cooking to be cooked over a fire; if a range is found in game they can in fact be cooked by players who have a Cooking level of 1 or higher. Cave morays are the highest healing fish found in Daemonheim and heal up to 2250 life points depending on one's Constitution level. Even with 99 Cooking a player can still burn cave morays; using the highest tiered branches available will help to reduce the amount of burnt fish.
The minimum Constitution level to receive the full amount of healing from this food is 90.
